Walker County was in the Alabama Power service area most impacted by Thursday night's storms.
The company reported on its Twitter page at 8:57 a.m. that 11,000 customers in western counties were still without power.
In Walker County, 4,140 customers were still waiting for power to be restored at 9:45 a.m, according to Britton Lightsey, the company's countywide manager.
The figure included 900 customers in east Walker (Dora, Sumiton, Sipsey, Empire), 2,660 customers in central Walker (Jasper, Cordova, Parrish, Oakman, Curry) and 580 in west Walker (Carbon Hill, Eldridge, Townley and Nauvoo).
Lightsey said all available resources were being dispatched to the company's western division, which includes Walker County.
"We've got resources coming in from less impacted areas, from out of the state, contractors. We're going to have a lot of people, especially on the western side of the state, which was the hardest hit," Lightsey said.
Alabama Power reported approximately 49,000 outages as of 7:55 p.m. Thursday as the storms were still making their way through Walker County.
